I am having trouble getting past the login loop after installing Ubuntu 16.04.3 on a Dell Precision Rack 7910 server.
As many others have had similar issues recently (https://devtalk.nvidia.com/default/topic/1024681/login-loop-with-ubuntu-16-04-with-nvidia-gtx-1060/, and https://devtalk.nvidia.com/default/topic/1027244/-solved-ubuntu-14-04-login-loop-after-installing-nvidia-384/), I tried all the suggested fixes I could find without any luck.
I started out with base Ubuntu 16.04.3 install. I noticed that I had 2 video cards: Matrox mgag200 and the Nvidia GM204GL Quadro M4000. Initially, I could login and the desktop came up as expected. When I looked at System Settings/Software & Updates/Additional Drivers, I noticed it was using the Matrox driver instead of the Nvidia. When I changed it to Nvidia and restarted the box, then the login loop began.
Some of the things I tried include:
- sudo apt-get dist-upgrade: this put me at Ubuntu 16.04.4
- blacklisting the mgag200 driver
- purging nvidia* and reinstalling using sudo ubuntu-drivers autoinstall
I’m including a generated nvidia-bug report. Hopefully someone smarter than I can help shed some light on this.
Thanks in advance!
